Development and Characterization of High Performance and Robust Mixed Conducting Cathodes Supportive of Lower Cost Solid Oxide Fuel Cells

The University of South Carolina will team with LG Fuel Cell Systems (LGFCS) to develop mixed electronic and ionic conducting cathode materials for durable and robust low-cost solid oxide fuel cells (SOFCs). The intention of this research is to improve SOFC power density over the entire operational temperature range (550 to 900C) by using mixed ionic and electronic conducting nickelate-based cathodes on a dense barrier layer, and evaluate their performance in comparison to more established cathode materials.

Project Benefits

This core technology work provides a platform for more detailed understanding of cathodes, which can yield higher power densities while achieving lower system costs. Knowledge will be generated about the barrier layer and physical properties of layered compounds and provide answers to questions on obstacles to commercial viability of reliable, robust, and durable SOFC technology.
